Term
What are the Characteristics of Systems?
Definition

A system is

  1. made of individual parts that work together as a whole
  2. usually connected to one or more other system 
Term
Name the 11 systems of the human body:
Definition

Human Body Systems

 

Circulatory          Respiratory

Digestive            Excretory

Immune          Endocrine

Reproductive          Integumentary

Skeletal          Muscular

Nervous                      

Term
What are the functions of the Circulatory System?
Definition
  • transports blood, nutrients, gasses and wastes
  •  
  • (nutrient=  chemicals needed for survival)
Term
What are the functions of the Digestive System?
Definition
  • takes in food
  • breaks down food
  • absorbs nutrients
  • eliminates solid waste
Term
What are the functions of the Respiratory System?
Definition
  • controls breathing
  • exchanges gases in lungs and tissues
  • ie exchange of O2 and CO2
Term
What are the functions of the Excretory System?
Definition
removes liquid and gas wastes from the body
Term
What are the functions of the Immune System?
Definition
defends the body against infections
Term
What are the functions of the Endocrine System?
Definition
  • manufactures and releases hormones
  • hormones regulate various bodily functions
Term

What are the functions of the Reproductive Systems?

 

 

(Note some functions are identical,

some differ in male and female)

Definition
  • includes reproductive organs for producing gametes/ for creation of offspring
  • includes hormone producing organs which determine characteristics specific to male or female organism

 

Term
What are the functions of the Integumentary System?
Definition
  • The Integumentary System includes:
  •  skin, hair, and nails.
  •  
  • These create a waterproof, protective barrier around the body.
Term
What is the function of the Skeletal System?
Definition
  • supports the body
  • gives shape
  • protects parts of the body
  • works with the muscles to move parts of the body
Term
What are the functions of the Muscular System?
Definition
  • muscles work with bones to move parts of the body
  • some assist organ function (stomach organ muscle)
  • some muscles are an organ - the heart
Term
What are the functions of the Nervous System?
Definition
  • detects changes in the environment and brain signals response changes to the body

 

  • sends signals to body parts for normal functions
Term
Define: Organ System
Definition
  •  a group of (1 or more) organs that perform specific bodily functions
Term
Define: tissues
Definition

Cells of the same structure and function

(are the same tissue)

Term
Name the Tissue groups in the Human Body:
Definition

Muscle       Tissue

Nerve        Tissue

Connective Tissue

Epithelial   Tissue

Term
Name some functions of muscle tissues:
Definition
  • skeletal muscles assist the body in movement
  •  
  • specific functions IE. heart muscles for pumping blood
Term
What are the functions of the Nerve tissues?
Definition
  • -transfer signals in the body and its organs
  • -to tell the body how to respond to changes in its internal and external environments
Term
What are the functions of connective tissues?
Definition
  • -hold together and supports other tissues, such as skeletal connective tissue
  • - connective tissue connects, protects and insulates organs
Term
What are the functions of Epitherlial Tissue?
Definition

- cover the surface of organs and the body

-line the inside of body parts such as mouth, esophagus and stomach
